Olympus CX21 - Educational Microscope Specifications
The CX21 sets a new standard in educational microscopy for biological applications. Solid, easy to operate and reliable for routine educational users. The CX21 has a sturdy, compact frame with a slightly smaller footprint than the CX31. The CX21 design is similar to the CH20 but with added features including infinity corrected optics and universal power supply for 100-120v/220-240v. The CX21 comes with an improved mechanical rackless stage and the same student proofing as the CX31 microscope.
